F/Qfl/VK e5.BUG/V0 14, JM Mm fiTTOE/VE'YS u i i 3,690,958 Patented May 28, 1963 Thisinvention relates to an improved urinary drainage bag assembly and, moreparticularly, to an improved hanger for a disposable urinary drainagebag.

It is an object of the present invention to provide an improved hangerparticularly suitable for use in supporting a disposable urinarydrainage bag at the side of a hospital bed or in some other suitablelocation and which is of improved construction so that it may be readilyassembled with and disassembled from the drainage bag.

A further object is the provision of an improved hanger for urinarydrainage bags of the above character having an improved arrangement forguiding the drainage tube into the drainage bag so that there is nointerference between the hanger and drainage tube and so that thedrainage tube will properly drain into the bag.

My invention contemplates the provision of an improved hanger for adisposable urinary drainage bag in the form of a wireframe havingtransverse supporting and hanger bars interconnected by side members andhaving a bracket mounted on the Wire frame adjacent one side thereof andextending downwardly at a laterally inclined angle and terminating in asimilarly inclined U-shaped drainage tube guide below the hanger bar.

In the accompanying drawing FIG. 1 is a perspective view of a urinarydrainage bag assembly having a hanger embodying my invention;

FIG. 2 is a longitudinal sectional view in the direction of the arrowson the line 22 of FIG. 1; and

FIG. 3 is a cross sectional view in the direction of th arrows on theline 3-3 of FIG. 1.

In the drawing I have shown a urinary drainage bag suitably supported onmy improved hanger 12 which in turn is supported from the rail 14 of ahospital bed. A drainage tube 16 leading from the patient in the bed issupported by the guide bracket mounted on the hanger in such a manner asnot to interfere therewith and so as to discharge into the drainage bag10.

The drainage bag 10 may be of any desired type having a tubular culf orhem at the upper end thereof so as to be supportable by the hanger. Inthe accompanying drawing I have shown one type of disposable urinarydrainage bag made of a suitable, transparent, flexible plastic materialwhich is inert to the contents thereof. For this purpose I have foundthat sheet plastic material made of polyethylene, polypropylene,polyvinyl chloride or its copolymers serves very satisfactorily. The bagis made of two layers of plastic sheet material which may be integrallyconnected together at its lower and upper ends as shown at 18 and 20 andis heat sealed adjacent its side edges 22 and 24; The heat seal 22extends from the bottom of the bag to a point adjacent the top edge ofthe bag where it meets a transverse heat seal 26 extending across thebag a short distance from the connected top edge 20 thus forming atubular hem or cuff through which a portion of the hanger may extend tosupport the bag.

The heat seal 24 extends from the lower edge of the bag to a shortdistance from the transverse seal 26 leaving an opening 28 through whichthe drainage tube 16 may be inserted into the bag and through which thebag may be subsequently emptied if desired.

My improved hanger 12 is preferably in the form of a frame made of metalwire. The metal wire is preferably of a type which is resilient andwhich is corrosion-resistant so as to be unaffected by the material tobe drained into the bag. For this purpose I have found that stainlesssteel, nickel plated or vinyl coated steel, copper-nickel alloy andmarine bronze serve satisfactorily.

The wire frame comprises generally a supporting bar 30 extendingtransversely of the upper portion of the hanger and preferably havingintegral eyes or loops 32 formed by twisting the wire of the supportingbar upon itself. The wire frame is also provided with a hanger bar 34 ofgreater length than the supporting bar 30 and extending transversely ofthe lower portion of the wire frame parallel to and in alignment withthe supporting bar. A first side member 36 is integrally connectedbetween one end of the supporting bar and hanger bar and is disposed atan outwardly inclined angle. A second side member 38 is integrallyconnected to the other'end of supporting bar 30 and extends downwardlyat an outwardly inclined angle terminating in a laterally-projectingupwardly facing U-shaped hook 40. The U-shaped hook 40 on side member 38is releasably engageable with the other end of the hanger bar 34 whichhas a complementary shaped, curved portion as shown most clearly in FIG.1.

The hanger is assembled with the drainage bag 10' by releasing thehanger bar 34 from the hook-shaped catch 40 and inserting the hanger barthrough the tubular hem or cuff formed at the upper end of the drainagebag. The end of hanger bar 34 is then engaged with the hookshaped catchas shown in FIG. 1.

The hanger may be supported in a suitable manner as from a bedrail 14 bymeans of a hanger cord such as shown at 42 which is extended through thetwo eyes 32 and secured together in endless fashion. One portion of thehanger cord may be extended through the aperture in the hanger, hook orclip 44 and the other portion of the hanger cord may be extended aroundthe bed rail as shown and engaged with a hook on the end of the clip.The cord can then be adjusted so that the drainage bag is suspended inhorizontal fashion. If desired, the hanger cord may simply be suspendedfrom a suitable projection such as a hook or rod.

I also preferably provide a suitable bracket formed with a guide for thedrainage tube preferably arranged so that the hanger will not interferewith the drainage tube and so that liquid is free to readily drainthrough the tube into the bag.

For this purpose I provide a bracket 46 made of wire and secured to thefirst side member 36 and the hanger 34 at a position near the side orend of the hanger. The bracket depends downwardly at an outwardlyinclined angle and terminates in a similarly inclined U-shaped drainagetube guide 48 positioned below the hanger bar. The wire bracket as shownis made of an elongated strip of wire folded upon itself so as toprovide two spaced parallel-wire members connected together at the freeend thereof. The U-shaped guide 48 is of a size to accommodate and holdin place a drainage tube 16. The spacing between the Wire members issuch that an elastic washer or collar 50 assembled around the drainagetube 16 and preferably bonded thereto can be accommodated between thetwo wire members in the guide as shown. The washer fits snugly aroundthe drainage tube, and it serves to properly position the drainage tubein the guide and also serves as a stop to prevent accidental withdrawalof the drainage tube from the drainage bag.

In using my improved hanger for disposable urinary drainage bags I firstrelease the free end of hanger bar 34 from interengagement with thecatch 40 and assemble the tubular seam or cult of a disposable drainagebag over the'hanger bar. I then interengage the free end of the hangerbar with the catch 40 as shown in FIG. 1. The assembly is then suspendedin a suitable position as from the rail of a hospital bed by eXtendingthe hanger cord 42 around the rail of the bed and engaging it with thehook of the clip 44. The assembly is then adjusted so that the drainagebag is suspended in substantially hori zontalposition.

The drainage tube 16 which is suitably connected to the patient isextended into the opening 28- in the drainage bag and engaged in thedrainange tube guide 48 in the manner shown with the collar 50positioned between the two wire members of the guide bracket.

It will thus be seen that the drainage tube can be assembled with thebag without any interference from the hanger and that the fluid is freeto drain through the tube without any obstruction.

At suitable intervals the disposable drainage bag is removed andreplaced with a new bag. The bag may be forwarded to the laboratory forsuitable tests on the material drained therein. Under any circumstancesthe bag need not be cleaned and sterilized, for reuse, but can bediscarded.

It will thus be seen that I have provided an improved urinary drainagebag assembly having an improved hanger that can be readily assembledwith and disassembled from disposable drainage bags; which can bereadily suspended in a suitable position as from a hospital bed; andwhich is provided with an improved guide bracket for retaining andguiding a drainage tube without interference with the hanger and so thatthe fluid may readily drain therethrough into the drainage bag.
